11 and 12 researched events on one shared scale. Argus 1931–present, Polaroid 1932–present.
The axis stretches where either maker has research and collapses where neither does, so a year sits opposite the same year on both. Event counts differ because research depth differs, not because one company did less.
International Radio Corporation built Kadette radios in molded cabinets in Ann Arbor. Charles Verschoor looked for a product that could keep the plant busy outside the radio season, and the company applied its plastics experience and mass-production ambitions to an inexpensive 35mm camera launched in May 1936.
The compact Model A paired a molded body and collapsible lens with a price far below imported miniature cameras. AF, B, A2B and A2F versions added focusing, a faster shutter-lens package, or exposure guidance, turning one successful idea into a family that helped normalize 35mm photography for American amateurs.
The C introduced rangefinder measurement, the C2 coupled it to the lens by an external gear, and the flash-synchronized C3 established the famous rectangular form. Its body-mounted shutter accepted a modest ecosystem of normal, wide and telephoto front assemblies from Argus and outside optical suppliers.

The K, 828-film M, A3, photoelectric-metered CC, postwar Model 19, A4 and C20 moved beyond the main A and C families. They tested half-frame options, built-in exposure aids, metal construction and streamlined forms, leaving a varied record of how Argus searched for the next durable amateur-camera formula.
Argoflex cameras carried Argus into 120 and 620 roll film, from the plastic E to Harley Earl-styled metal models and simplified Forty and Seventy-Five variants. The recalled Argoflex II, revised EM and EF, and later boxlike models show experimentation with film transport, flash and waist-level viewing.
Government work began before American entry into the war. In August 1942 Argus stopped civilian output, stored camera machinery and unfinished stock, and devoted the expanded Ann Arbor plant to military optical and radio equipment. The work broadened skills, employment and the factory complex before peacetime production returned.
The Model 21 brought a removable back, projected framelines, automatic shutter cocking and flash features. C4, C4R, C44 and C44R cameras developed that metal-bodied platform through coupled rangefinding, rapid advance and a proprietary interchangeable-lens system, distinct from the older C-series interface.

Sylvania reached an agreement to acquire Argus Cameras in 1956 and operated the business from 1957. The purchase placed the Ann Arbor maker inside a larger electronics company while its established cameras, projectors and optical products continued under the Argus name during a rapidly changing import market.

Standard and Match-Matic C3 editions refreshed the established camera, while C33 and Autronic models coupled exposure settings more closely to accessory meters or automatic controls. The changes made picture taking quicker but also reveal how Argus tried to update a body concept rooted in the late 1930s.
Mansfield Industries bought Argus in March 1962, and the combined concern adopted the Argus, Inc. name that May. Camera production moved away from Ann Arbor over the following years as the badge appeared on imported equipment, changing Argus from a predominantly local manufacturer into a broader photographic-products brand.
Domestic camera production had ended by 1969, though later imported and digital products reused the Argus name. The surviving Ann Arbor buildings, factory films, employee publications, collector surveys and the Argus Museum now preserve the manufacturing story and separate it from later trademark use.
Land and George Wheelwright built a Boston-area research company around synthetic polarizing sheet, moving from experimental rooms into purpose-built production. In 1937 new investment supported reincorporation as Polaroid Corporation and transferred the laboratory patents into the new firm.

Military and industrial optical work expanded Polaroid beyond sunglasses and camera filters. The company learned to manufacture coated materials and precision optical assemblies at scale, creating the interdisciplinary base of chemistry, mechanics and design that later supported instant photographic systems.

Land demonstrated instant photography in 1947, and the Model 95 reached customers in 1948. Its negative-positive roll-film process used camera rollers to spread reagent before the photographer peeled apart a finished print, relocating much of the darkroom process into a portable system.

The Model 95 opened a broad family of folding roll-film cameras, followed by higher-specification 110, 120, 150, 160, 700, 800 and 900 models and the smaller 80 series. Rangefinders, automatic exposure and supplier-made lenses differentiated equipment for casual and advanced photographers.

The Automatic 100 introduced pack loading and electronic exposure, then 100, 200, 300 and 400 series cameras varied body material, finder, timer, flash and lens. Manual 180, 190 and 195 models used Japanese shutters and named optics, giving the platform a professional branch.

The low-cost Swinger and its successors carried instant photography into youth culture and casual social use. Colorpack and other rigid-body pack-film cameras broadened the same idea, while portrait, identification, medical and industrial systems made immediate prints useful far beyond family snapshots.

The folding SX-70 combined reflex viewing, a collapsible mirror path, motorized ejection and integral film that developed in daylight. Alpha revisions improved the mechanism, Sonar added ultrasonic autofocus, and rigid-body OneStep and Pronto cameras translated the format into mass-market products.

Higher-speed 600 film supported flash-equipped box cameras and folding SLR 680/690 models. Spectra, called Image in several markets, used a wider integral format, while Captiva, i-Zone and JoyCam pursued different print shapes and uses. Similar styling did not make these film packs interchangeable.

Polaroid prevailed in its instant-photography patent case against Kodak, leading Kodak to leave the field in 1986. Yet dependence on chemical instant imaging became a liability as digital photography grew. The original Polaroid Corporation entered Chapter 11 in 2001 after a difficult diversification.

Assets and the Polaroid name passed through a reorganized company and later Petters Group ownership. Instant camera production and the remaining film lines stopped in 2008, and the post-reorganization company entered bankruptcy that December amid the wider collapse of the Petters organization.
The Impossible Project organized around Polaroid's surviving Enschede plant and rebuilt integral-film production with altered materials and supply chains. Film sales resumed in 2010, preserving the physical Polaroid format even though the original Cambridge corporation and its formulas did not continue intact.

In 2017 the majority shareholders behind the Impossible Project acquired PLR IP Holdings, owner of the Polaroid brand. Polaroid Originals followed, and the businesses were integrated under Polaroid B.V.; the current company again develops instant cameras and manufactures film at Enschede.
